[0208] Throughout the figures, the same reference numerals are used to refer to corresponding components or to components that have a corresponding function.

[0209] FIG. 1 schematically depicts an embodiment of the artificial fireplace according to the present invention, to which is referred with reference numeral 1. The artificial fireplace 1 comprises a housing 2, in which an opening 3 is provided. The housing 1 defines an interior 4 and the opening 3 is configured to provide access into the interior 4. The opening 3 is arranged at the front of the housing 2 and allows a line of sight (S) into the interior 4 of the housing 2. In the figures, the line of sight (S) is displayed be aligned in a horizontal direction, but any line along which users may look into the interior 4 of the housing 2 may be regarded as a line of sight.

[0210] In the present embodiment, the opening 3 in the housing 2 is covered with a glass pane. The glass pane is transparent for light in the visual regime, and thus allows a user to look into the interior 4 of the housing 2. Alternatively, the glass pane may also be omitted to reduce any disturbance upon looking into the interior 4 of the housing 2.

[0211] The artificial fireplace 1 further comprises a semi-transparent mirror 10, which is arranged in the interior 4 of the housing 2. The mirror 10 can also be seen in FIGS. 2 and 3. The semi-transparent mirror 10 is set at a non-right angle with respect to a horizontal direction (H) and a vertical direction (V). In the present embodiment, the angle is set at 45°. The semi-transparent mirror 10 is fixed with respect to the housing 2. At the front of the housing 2, the mirror 10 is mounted in a cross bar 11, which extends across the width of the housing 2 and in front of the opening 3 in the housing 2. The cross bar 11 is further arranged to cover a frontal edge of the mirror 10, in order to give the impression that no mirror 10 is provided at all.

[0212] The semi-transparent mirror 10 comprises a first side 12, which faces the opening 3 in the housing 2 and which is partly aligned in an upward vertical direction as well. The first side 12 of the mirror 10 is configured to at least partially reflect a video that is displayed towards it.

[0213] The semi-transparent mirror 10 comprises a second side 13, which is arranged opposite to the first side 12, and which faces the away from the opening 3. The second side 13 is partly aligned in a downwards vertical direction as well. The second side 13 of the mirror 10 is configured to at least partially transmit a video that is displayed towards it.

[0214] The mirror 10 is configured to transmit the beam from its second side 13 towards the first side 12. At the first side 12, the transmitted beam from the second side 13 and the reflected beam from the first side 12 are recombined and a combined beam is emitted from the first side 12. Due to the orientation of the mirror 10 at 45° with respect to the vertical direction (V) and the horizontal direction (H), the first display device 20 may be arranged substantially horizontally, configured to display the first video of flames in the downward vertical direction (V) and the second display device 30 may be arranged substantially vertically, configured to display the second video in the horizontal direction (H).

[0215] The artificial fireplace 1 comprises a first display device 20, which is arranged in the interior 4 of the housing 2 at a top portion of the housing 2. In the present embodiment, the first display device 20 is provided as a flat-screen monitor 20, which is configured to emit a first light beam 21 in the downward vertical direction (V). The first light beam 21 is thereby projected onto the first side 12 of the semi-transparent mirror 10, where it is at least partially reflected thought the opening 3 in the housing 2. The first video of flames 22 may be comprised in the emitted first light beam 21, such that the emitting of the first light beam 21 by the first display device 20 corresponds to the displaying of the first video of flames 22.

[0216] The artificial fireplace 1 further comprises a second display device 30, which is arranged in the interior 4 of the housing 2, at a rear portion thereof. The second display device 30 is, in the present embodiment, a flat-screen monitor 30 as well, which extends in the vertical direction (V). The second display device 30 is configured to emit a second light beam 31 in the horizontal direction (H), onto the second side 13 of the semi-transparent mirror 10, where the second light beam 31 is at least partially transmitted towards the first side 12 of the mirror 10. The second video 32 may be comprised in the emitted second light beam 31, such that the emitting of the second light beam 31 by the second display device 30 corresponds to the displaying of the second video 32.

[0217] The mirror 10 is configured to recombine the first light beam 21 and the second light beam 31, and to transmit this combined beam through the opening 3, along the line of sight (S). Since the first light beam 21 is reflected on the first side 12 of the mirror 10, it appears, when seen along the line of sight (S), that the first light beam 21 originates from a virtual vertical plane 21′ that intersects the mirror 10. In FIG. 3a, this virtual vertical plane 21′ is indicated by the dashed line.

[0218] The second light beam 31 originates from the second display device 30 and is emitted in the horizontal direction (H), which is substantially parallel to the line of sight (S). Also for users, which look into the housing 2 though the opening 3 and along the line of sight (S), the second light beam 31 appears to originate from the rear portion of the housing 2, whereas the first light beam 21 appears to originate from the virtual vertical plane 21′. For the user, it thus appears that there is a spacing Δ in between the projections of the first light beam 21 and the second light beam 31. In FIG. 2b, this spacing Δ between the light beams 21, 31 is shown schematically.

[0219] In this embodiment of the artificial fireplace 1, the first light beam 21 comprises the first video of flames 22 and the second light beam 31 comprises the second video of flames 32. Both videos have been extracted from a recorded video of an actual fire and thus form an accurate display of flames. Alternatively, the first video and second video may also be rendered videos of a virtual fire, which can, for example, be rendered real-time by a controller of the artificial fireplace.

[0220] The artificial fireplace 1 further comprises a grid 40, which is arranged in the interior 4 of the housing 2. The grid 40 extends at least partially in the horizontal direction (H) and has a lattice-like structure, defining through openings. The grid 40 has a first side 41, which faces at least partially in the upwards vertical direction. A front portion of the grid 40 is slightly bent in a downwards direction and extends towards a bottom edge of the housing 2, adjacent the opening 3.

[0221] The artificial fireplace 1 comprises an artificial fireplace element 50, which comprises a plurality of element parts, which are arranged in a stacked configuration and which are arranged in the interior 4 of the housing 2 as well. The artificial fireplace element 50 resembles a physical fireplace element in an actual fireplace and resembles, in the present embodiment of the artificial fireplace 1, stacked wooden logs in a wood fire.

[0222] The artificial fireplace element 50 is arranged on the grid 40 and the element parts are stacked, in order to resemble actual wooden logs. The artificial fireplace element 50 is arranged in between the semi-transparent mirror 10 and the second display device 30 and the second side 13 of the mirror 10 faces the artificial fireplace element 50.

[0223] It is displayed in FIG. 3b that a frontal surface 51 of at least one of the element parts of the artificial fireplace element 50 is aligned parallel to the virtual vertical plane 21′ of the first light beam 21. This at least one element part does therefore not intersect with the virtual vertical plane 21′, and the vertical frontal surface 51 allows for accurate focusing of the first light beam 21 and allow a user to experience the flames in the first video 22 to appear to originate from the first vertical plane 21′.

[0224] The artificial fireplace element 50 is arranged in between the virtual vertical plane 21′, from which the first light beam 21 appears to originate, and the second display device 30, from which the second light beam 31 originates. Both light beams 21, 31 comprise videos of flames 22, 32, such that a three-dimensional flame effect is achieved. Hence, it appears that there are flames both in front of or on the artificial fireplace element 50 and behind the artificial fireplace element 50.

[0225] The artificial fireplace 1 further comprises a light source, which is in the present embodiment embodied as a strip of LEDs 52 that is arranged in the interior 4 of the housing 2, at the top portion thereof. The strip of LEDs 52 extends over substantially the entire width of the housing 2 and is configured to illuminate the artificial fireplace element 50 that is arranged below. As such, the illuminated artificial fireplace element 50 has, for the users, an improved visibility within the interior 4 of the housing 2. The fireplace 1 further comprises a shielding 53, which is arranged in front of the strip of LEDs 52 and which is configured to prevent the emitted light from the strip of LEDs 52 from directly reaching the opening 3 in the housing 2.

[0226] The artificial fireplace 1 further comprises a plurality of second light sources 54, which are arranged in the interior 4 as well. The second light sources comprise a plurality of lamps 54, which extend over the width of the housing 2 and which are spaced with respect to each other. The lamps 54 are arranged below the grid 40 and face toward a second side 42 of the grid 40, which is arranged opposite to the first side 41 and which faces at least partially in a downwards direction.

[0227] The lamps 54 are configured to illuminate the artificial fireplace element 50 as well. The light from the lamps 54 passes through the openings in the grid 40 and shines on the artificial fireplace element 50. The lattice of the grid 40 causes a grid-like shadow on the artificial fireplace element 50, since only the light that passes through the openings in the grid 40 reaches the artificial fireplace element 50. This grid-like shadow creates a carbonated effect on the artificial fireplace element 50, which makes element parts to resemble carbonized wooden logs.

[0228] Preferably, the lamps 54 emit light in the visible regime, having a wavelength that corresponds to a light colour in the spectrum between red and yellow, to resemble a glowing effect of the artificial fireplace element 50. The lamps 54 are controlled by a controller 62 to emit light with an intensity that varies over time, in order to achieve an even more realistic glowing effect of the artificial fireplace element 50. The controller 62 is configured to synchronize the changes in intensity with the pattern of flames that is displayed in the first and second videos 22, 32 in the first and second light beams 21, 31.

[0229] In between the bottom edge of the opening 3 in the housing 2 and the cross bar 11, a lower portion 3′ of the opening 3 allows a user to look at a portion of the grid 40. Here, the light from the lamps 54 is visible as well. Preferably, but not displayed in the figures, comprises the artificial fireplace 1 a large amount of reflective scattering elements, which are arranged on the first side 41 of the grid 40. The reflective elements may for example be glass fragments, which are configured to reflect and scatter incident light beams. The glass elements are configured to reflect and scatter the light that is emitted by the lamps 54, coming from below through the openings in the grid 40, in order to resemble glowing embers on the grid 40. These glass elements are visible through the lower portion 3′ and provide that the artificial fireplace 1 resembles an actual fireplace even more realistically.

[0230] The artificial fireplace further comprises a sound device 60 and a heating device 61. The sound device 60 is arranged on top of the housing 2 and is configured to emit a sound signal that resembles the sound of an actual wood fire in an actual fireplace. The heating device 61 is arranged in the interior 4 of the housing 2, below the opening 3, and is configured to emit heat radiation. The emitted heat radiation mimics the heat that is generated by an actual fire in an actual fireplace and may serve the purpose of creating a more realistic artificial fireplace 1, but may even contribute in heating a room in which the artificial fireplace 1 were to be installed. Preferably, the housing 2 comprises vent holes at its front, below the opening 3, in order to allow the escape of the heat radiation from the heating device 61. In the embodiment that is shown the figures, the sound device 60 is located above the opening 3 and the heating device 61 is arranged below the opening 3. According to the present invention, the sound device and the heating device may as well be located at other positions in the artificial fireplace.

[0231] The artificial fireplace 1 further comprises a controller 62 and a digital storage device 63. The controller 62 is electrically connected to the first display device 20 and to the second display device 30 and is configured to control the display devices 20, 30. The controller 62 is furthermore connected to the storage device 63. The storage device 63 comprises at least the first video 22 and the second video 32, which are stored on the storage device 63. The storage device 63 is, in the present embodiment, provided as a media player, which is connected to the display devices 20, 30 in order to emit the light beams 21, 31 with the videos 22, 32.

[0232] The storage device 63, with the first video 22 and the second video 32 stored thereon, and the artificial fireplace element 50 together form a fireplace element assembly. In case the user is interested in a different artificial fire pattern of the artificial fireplace 1, he or she may provide a different fireplace element assembly and may replace the artificial fireplace element 50 of the present assembly with the artificial fireplace element of the replacement assembly, which may have element parts that are stacked in a different configuration. The storage device of the replacement assembly comprises different first and second videos, which correspond to the artificial fireplace element of the replacement assembly. Preferably, the videos on the storage device of the replacement assembly have been extracted from a recorded video of an actual fire in which that physical fireplace element was arranged similarly as the artificial fireplace element of the replacement assembly. When these different videos are projected in the first and second light beams, the artificial fire pattern that is generated by the artificial fireplace changes and the user can have a different fireplace impression, without having to replace the entire artificial fireplace 1.

[0233] FIG. 4a depicts an example of a recorded video of an actual fire in an actual fireplace. The actual fire can be a wood fire, but in the current embodiment, the actual fire is a gas fire. In the present embodiment, the recorded video is recorded from an actual gas fire on a physical fire element that represents wooden logs, as if the actual gas fire actually were a wood fire.

[0234] After the video has been recorded, a first video 22 and a second video 32 are extracted therefrom. This extraction is, at least in the present embodiment, carried by means of appropriate software that allows a user to spread the contents of a single video over multiple videos.

[0235] The single recorded video comprises all flames that are present in the actual fireplace. By means of the extraction, flames from different areas in the actual fire may be isolated in order to form multiple videos, which each comprise an image of the flames at a different area in the actual fireplace.

[0236] In FIG. 4b, the emitted first light beam 21 is displayed, which comprises the first video 22. The first video 22 is extracted from the recorded video and comprises recorded flames 23 that originate from a first area in the actual fire. This first area is generally chosen to be an area that is, when seen along a line of sight, located at a front part of the actual fire and of the physical fireplace element and which is, in the present embodiment, aligned perpendicular to the line of sight. Hence, when the first video 22 is displayed in the artificial fireplace 1, it appears that the flames 23 therein originate from the virtual vertical plane 21′, which is arranged at a front part of the artificial fireplace element 50.

[0237] In FIG. 4c, the emitted second light beam 31 is displayed, which comprises the second video 32. The second video 32 is extracted from the recorded video as well and comprises recorded flames 33 that originate from a second area in the actual fire. The second area in the actual fire is spaced from the first area and is, when seen along the line of sight, arranged at a rear part of the actual fire and of the physical fireplace element. The second plane is, in the present embodiment, aligned perpendicular to the line of sight as well.

[0238] During use of the artificial fireplace 1, the second video 32 is projected from the second display device 30, which is arranged behind the artificial fireplace element 50. It thereby also appears that the flames 33 in the second video 32 also originate from behind the artificial fireplace element 50.

[0239] The second video 32 not only comprises the recorded flames 33, but also comprises a video 34 of a glow effect on a background of the physical fireplace, which is extracted from the recorded video as well. This video of the glow effect 34 comprises the glow effect of the background of the actual fireplace, being illuminated by the flames of the actual fire. In FIG. 4c, the glow effect is indicated by the dashed line.

[0240] The first video 22 and the second video 32 are stored on the storage device 63 of the artificial fireplace 1 and the controller 62 is configured to control the first display device 20 to emit the first light beam 21 with the first video 22 and to control the second display device 30 to emit the second light beam 31 with the first video 32.

[0241] The storage device 63 furthermore comprises a plurality of further first videos and further second videos. The further first videos and second have been extracted from a recorded similarly as the first video 22 and the second video 32, but the respective recorded videos have been recorded of an actual gas fire having a different gas fire setting. In the present embodiment, the gas fire setting is a setting for the amount of gas supply towards the actual gas fire. A high gas fire setting corresponds to a large gas supply and a high intensity of the actual gas fire, whereas a low gas fire setting corresponds to a small gas supply and a low intensity of the actual gas fire.

[0242] For obtaining of the further first second videos, first, a gas fire setting is stored. Then, a respective video is recorded, which is extracted in a respective first video and second video, which are stored and are linked to the respective gas fire setting.

[0243] The artificial fireplace 1 comprises an input device. In the present embodiment, the input device may be a rotatable knob 64, which is connected to the controller 62. The knob 64 allows a user of the artificial fireplace 1 to set a parameter for the artificial fire pattern that is to be displayed with the artificial fireplace 1. In an alternative embodiment, the input device may be a remote control device or may be a mobile communication device, such as a smartphone, on which an application is installed to control the artificial fireplace. The input device may for example be formed by one or more buttons on the remote control device or may be formed by a virtual slider in the application on the mobile communication device.

[0244] The parameter may for example represent an intensity of the displayed artificial fire pattern. The controller 62 is configured to select the one of the gas fire settings for the actual gas fire that are associated with the set parameter. Subsequently, the controller 62 is configured to select the respective first video 22 and second video 32 that corresponds to the selected gas fire setting and is configured to control the first display device 20 to emit a first light beam 21 that comprises that respective first video 22 and to control the second display device 30 to emit a second light beam 31 that comprises that respective second video 32.

[0245] It may, however, as well occur that the set parameter does not correspond to a certain gas fire setting of the actual gas fire, but that it corresponds to a setting in between two consecutive gas fire settings. In this situation, the controller 62 may further be configured to control the first display device 20 to emit a first light beam 21 with a combination of first videos 22 and to control the second display device 30 to emit a second light beam 31 with a combination of second videos 32. The combination of first videos 22 may thereby be formed by a weighted average of the first videos 22 that corresponds to the consecutive gas fire settings and the combination of second videos 32 may be formed accordingly by a weighted average of the second videos 32 that corresponds to the consecutive gas fire settings as well.

[0246] The storage device 63 further comprises, for each of the gas fire settings, a setting value for the heating device 61. The heating output of the heating device 61, at a certain heating setting, preferably corresponds to the amount of heat that is generated by the actual gas fire at the corresponding gas fire setting. As such, the heating device 61 is configured to generate a realistic amount of heat that corresponds to the artificial fire pattern that is displayed by the actual fireplace 1.

[0247] Alternatively, the actual fire in the actual fireplace may also be a wood fire, which may be subject to certain conditions, such as a certain air flow towards the fire. The conditions for the wood fire may thereby form the fire settings, at least in case the fire in the actual fireplace were to be a wood fire.

[0248] The artificial fireplace 1 is configured to display an artificial fire pattern 70. A schematic representation of the artificial fire pattern 70 is visible in the artificial fireplace 1 in FIG. 2a. The artificial fire pattern 70 is, at least in the present embodiment, provided by the first light beam 21 and the second light beam 31. The first light beam 21 thereby comprises a first video 22, comprising recorded flames 23, and the second light beam 31 comprises a second video 32, comprising recorded flames 33.

[0249] For providing the first video 22 and the second video 32, a video is recorded of an actual fire pattern of an actual fire. In FIG. 5, the process of the providing of the videos 22, 32 and the displaying of the artificial fire pattern 70 is schematically displayed.

[0250] First, a physical fireplace element 101, comprising a plurality of stacked physical element parts, is arranged in an actual fireplace 100, or an actual fireplace is provided in which the physical fireplace element is already arranged. Preferably, the element parts of the physical fireplace element 101 are interconnected in order to assure their relative positions and to assure the position of the physical fireplace element 101 within the actual fireplace 100. The physical fireplace element may, in an embodiment, comprise wooden logs. In the present embodiment, the physical fireplace element 101 are provided as flame-resistant imitation logs 101, which resemble actual wooden logs, but which are able to resist heat.

[0251] The element parts of the physical fireplace element 101 are provided with gas channels, through which a flammable gas is guided. At the ends of these channels, the gas may escape into the actual fireplace 100 and is ignited in order to create an actual gas fire 102 on the physical fireplace element 101. The flames of the actual gas fire 102 form an actual fire pattern 103 on the physical fireplace element 101. The actual gas fire 102 and corresponding actual fire pattern 103 are displayed in FIG. 5b.

[0252] The actual fire pattern 103 varies with respect to the depth in the actual fireplace 100, parallel to a line of sight and perpendicular to the plane of FIG. 5. At the front of the actual fireplace 100, a first area 100′ is located. Towards the rear of the actual fireplace 100, a second area 100″ is located. The second area 100″ is, when seen perpendicular to the plane of FIG. 5, set a distance from the first area 100′, e.g. towards the back of the actual fireplace 100.

[0253] The first area 100′ and second area 100″ may be defined as regions in the actual fire 102, which span along a distance into the physical fireplace 100, seen along the line of sight. The first are 100′ is thereby provided in a proximal depth region in the actual fire 102 and the second area 100″ in the actual fire 102 corresponds to a distal depth region in the actual fire 102.

[0254] For the providing of the first video 22 and the second video 32, first, a video is recorded from the actual fire pattern 103 in the actual fireplace 101. In FIG. 5b, an image is displayed which represents the recorded video.

[0255] The recorded video is extracted into a first video 22, which comprises flames that originate from the first area 100′ and which form a respective actual fire pattern 103′. In FIG. 5c, an image is displayed which represents the extracted first video 22. The recorded video is further extracted into a second video 32, which comprises flames that originate from the second area 100″ and which form a respective actual fire pattern 103″. In FIG. 5d, an image is displayed which represents the extracted second video 32.

[0256] The recorded first video 22 and second video 32 are stored on the storage device 61 of the artificial fireplace 1.

[0257] In the actual fireplace 100, the gas fire setting may be changed in order to change the gas supply and to increase or decrease the intensity of the actual gas fire 102. For each of the gas fire settings, a video may be recorded of the actual fire pattern at both the first area 100′ and the second area 100″. The corresponding extracted first videos 22 and second videos 32 are stored together with their respective gas fire settings on the storage device 63 of the artificial fireplace 1.

[0258] In FIG. 5e, element parts of the artificial fireplace element 50 are shown, which are arranged in an interior 4 of an artificial fireplace 1. For the displaying of the artificial fire pattern 70, first, the artificial fireplace element 50 is positioned in the interior 4, such that its position corresponds to the position of the physical fireplace element 101 in the actual fireplace 100. This adapting may comprise the arranging of the individual element parts of the artificial fireplace element 50 with respect to each other, but may also comprise moving of the artificial fireplace element 50 itself, e.g. in the entire stacked configuration. The double-sided arrow in between the drawings in FIG. 5e indicates the comparison between the position of the physical fireplace element 101 in the physical fireplace 100 and the position of the artificial fireplace element 50 in the interior 4 of the artificial fireplace 1.

[0259] Preferably, the element parts of the artificial fireplace element 50 are connected to each other in a stacked configuration that corresponds to the stacked configuration of the element parts of the physical fireplace element 101 in the actual fireplace 100. More preferable, the artificial fireplace element 50 comprises an alignment portion, which is configured to mate with an alignment portion in the artificial fireplace 1 in order to ensure correct positioning of the artificial fireplace element 50 in the artificial fireplace 1.

[0260] Then, the first light beam 21 may be tuned in the artificial fireplace 1, in order to shift a position of the first video 22 with the first light beam 21. The first light beam 21 is adjusted such that, when seen along the line of sight (S) into the artificial fireplace 1, the first video 22 is aligned with the artificial fireplace element 50 in the interior 4 of the artificial fireplace 1. This step of tuning of the first light beam 21 is schematically displayed in FIG. 5f.

[0261] Upon tuning, the flames in the first video 22 become aligned with the artificial fireplace element 50, as if they actually originated from the artificial fireplace element 50 in the artificial fireplace 1, instead of originating from the physical fireplace element 101 in the actual fireplace 100.

[0262] In the present embodiment, the same may be done for the second light beam 31, which comprises the second video 32. The second light beam 31 is tuned as well, in order to align the flames in the second video 32 with the artificial fireplace element 50, so that it appears that the flames in the second video 32 actually originate from the artificial fireplace element 50 in the artificial fireplace 1, instead of originating from the physical fireplace element 101 in the actual fireplace 100. This step of tuning of the second light beam 31 is schematically displayed in FIG. 5g.

[0263] The tuning of the first light beam 21 and of the second light beam 31 may be done by tuning of the first display device 20 and the second display device 30, so as shift the position from the which the first light beam 21 and the second light beam 31 are emitted. Preferably, this shifting of the emitting position on the first display device 20 and the second display device 30 is controlled by means of the controller 62 of the artificial fireplace 1. Alternatively or additionally, the first display device 20 and the second display device 30 may be shifted in their entirety with respect to the artificial fireplace element 50 in order to shift the first light beam 21 and the second light beam 31.

[0264] By tuning of the first light beam 21 and the second light beam 31 in the artificial fireplace 1, the displayed first video 22 and second video 32 are aligned with the artificial fireplace element 50, so that the first video 22, second video 32 and the artificial fireplace element 50 along the line of sight (S) together form an artificial fire pattern 70 that resembles the actual fire pattern 103 in the actual fireplace 100, as is displayed in FIG. 5h.

[0265] In an additional embodiment of the method, the second video 32′ further comprises a glow effect 104 on the background in the actual fireplace 100. This is schematically displayed in FIG. 5i, in which it is shown that the second video represents an actual fire pattern 103″ on the second area 100″ in the actual fireplace 100 and a glow effect 104 on a background of the actual fireplace 100.

[0266] The tuning of the second light beam 21 with the second video 32′ now also comprises the adjusting of the position of the glow effect 34 with respect to the artificial fireplace element 50 in the artificial fireplace 1, as is schematically displayed in FIG. 5j. Hence, the glow effect 34 forms part of the second video 32′, so when the second light beam 31 is tuned to adjust a position of the flames 33 in the second video 32′, the position of the glow effect 34 is automatically adjusted accordingly. In FIG. 5k, the glow effect 34 is shown to be aligned in the artificial fireplace 1 as well, forming part of the artificial fire pattern 70′.

[0267] In a further additional embodiment, as displayed in FIG. 5l, the first video 22′ further comprises an additional animation 35. The additional animation 35 is, in the present embodiment, a cartoon figure. However, the additional animation may as well comprise advertising content or the like, or may comprise additional images or videos to, for example, adapt the displayed artificial fire pattern to the surroundings of the artificial fireplace 1. The additional image or video may thereto, for example, comprise a colouring that corresponds to a colour pattern outside the artificial fireplace 1.
